Hi I'm new here. Just had a quick question. I was thinking about putting 2 anteenas on my roof to pick up a more OTA broadcast stations. I will probably use the same mast to mount them. Will using 2 antennas adversely effect my picture quality in anyway? Thanks Tim
If they are pointing in different directions then you can use 2 sockets on the receiver, or combine them into one lead with a diplexer. All you need is to ensure that they are separated vertically by a distance equal to a minimum of a half a wavelength.
If you are pointing both in the same direction they can be joined together to increase signal with a phasing harness, which requires some maths to get it to work properly. They still need the vertical separation to work properly.
